i-3 Coaster Brake

Alternate views

The i-3 hub is an advancement on the legendary Sachs Torpedo three-speed gear hub. It's the core of a worry-free riding experience that lets you relax and enjoy the ride on your everyday routes.

Change gear any time: uphill, downhill, under load, or even standing still.

For i-3 riders, life is easy. Shifting is easy and reliable under any circumstances. The system is protected by its location inside your bike's frame, so it's well protected if the bike topples over. It's a great system for children, with features like its integrated coaster brake system and the easy-to-use BANDIX twist shifter for simple gear changes.
